IMPROVEMENT IN PAPER-TRIMMING MACHINES.

Specification forming part of Letters-Patent No. 168,963, dated Qctober 19, 1875; application filed March 27, 1875.

To all whom it may concern:

Be it known that I, DAVID THOMASBROUGH- TON, of Parkersburg, in the county of Wood and State of West Virginia, have invented a new and valuable Improvement in Border-Cutters and Paper-Trimmers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

l igure 1 of the drawings is a representation of a plan view of my machine, and Fig. 2 is a front view of the same. Fig.3 is a transverse vertical sectional view, and Fig. 4 is a sectional detail view.

This invention has relation to means for trimming and dividing paper and for cutting borders thereon; and it consists in the construction and novel arrangement of the feeding-rollers carrying the cutters, the adjustable roll-holder, and the receiving-shalt, as hereinafter fully shown and described.

In the accompanying drawings, the letter A designates the frame, consisting of the base A, the top A and the standards or end pieces 13 B connecting the two. 0 G designate the feeding and guiding rolls between which the paper passes trom the roll-holder to the receiving-shaft. The lower roll 0 is journaled at one end in a seatin the cleat D, which is secured to the base A transversely. The seat is open to the top of the cleatto facilitate the removal of the roll when necessary. The other end of the roll or roll-shaft is journaled in the end wall B, and is extended to receive the driving-pulley D Near the eleat this roller is provided With the annular disk-cutter a. The upper roll (1" is located immediately over the lower roll 0, and is also journaled in the end wall B. The opposite journal of this roll is seated in a pendent bracket, 1), being let into its seat laterally, the opening of the seat being seen at b on the side of the bracket.

This bracket is provided with a dovetail tenon,

outside the groove 6, and having its inner edge m in cutting contact with the disk-cutter a, is located the band-cutter a.

In order to regulate the cutting-friction, and to keep the'bracket D steady, a spring-brace E is secured to the frame and so arranged that its end bearingf will be at the lower part ot'the bracket opposite the cutting-edges ot' the cutters, or as nearly so as may be convenient. In order to regulate the pressure of this brace an adjusting cla-m 'rscrew, g, is provided. In front of the rollers G G are secured,- upon the front portions of cleats D D, parallel rails h h forming a raised track for the carriage k of the paper roll, which is provided on each side with longitudinal tenonst, adapted to slide in grooves l in the inside faces of the rails h. At one end of this carriage a standard, lchis provided, having a journalpin, m, designed to be introduced into the roll of paper at one end. Arranged to slide in a slot, 8, at the other end of the carriage, is an adjustable standard, k provided with an adjustable journal-pin, m, which serves to hold the other end of the roll of paper. It is apparent that within the limits of the frame the roll of paper may, by means of this carriage and its track, be located, so that the cutters will be opposite any desired point.

In rear of the rolls 0 O is located the receivingshaft G. This shaft is square in its sectional form in order that its purchase may be sufficient, and it is provided with a metallic cap or halt-sleeve, H, which embraces it on three sides, and serves to clamp the end of the paper strip. One end of the reel-shaft G is journaled in a seat, '0, connected with the standard B of the frame in such amanner that it can be readily removed from its seat. Th other end is squared and adapted to be introduced into a squared central aperture, 2, in a wheel or head-piece, z, attached to the inner end of the shaft of the friction-wheel L, which is provided with a rubber or other suitable arming, and engages with the drivingwheel-at the end of the machine; or gearwheels may be employed.

The paper roll having been mounted on the journal-pins ot' the carriage, and adjusted in.

proper position, its end is carried between the rolls 0 U and secured to the shaft G. Then the cutting is completed by turning the driv ing-wheel. If the receiving-shaft turns too slow, so that the paper is wound loosely, it may be turned up by means of the lever w. As the bracket and cleat, to which the inner ends of the rolls are journaled, are not in contact, there is provided a sufficient space for the passage of that part of the paper which is cut otf from the main strip, should it be of sufficient width to extend beyond the ends of the rolls,

What I claim as new, and desire to secure by Letters Patent, is

1. In apaper-trimming machine, the frame A, consisting of the base A, the top A, and

the standards B B,'with cleat D and pendent entbracket D and the adjustable spring-brace E,'substantially as and for the purpose set forth.

3. The square receiving-shaft G, provided with'a metallic cap or halt'-sleeve, H, substantiallv as and for the purpose setforth.

4. The parallel rails h h forming a raised track for the carriage k of the paper roll, the latter provided with longitudinal t enons t, adapted to slide in grooves lin the inside faces of the rails h, said carriage 75 being provided with standards 70%", substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

DAVID THOMAS BROUGHTON.
